Hello @scott_vanzuiden 
You will need to set those MyLab/Mastering links up each term, because of the way Pearson is set up - you create a course in Pearson, and it has to match your course in Canvas. I think this guide from Pearson will be helpful, but it has been awhile since I have used it: LMS Integration Services

I hope this is helpful,
Kelley
